Every Pixar movie has one minor character that steals the show — Edna from “The Incredibles,” Dory from “Finding Nemo,” the aliens from “Toy Story,” Boo from “Monster’s Inc.” and Heimlich from “A Bug’s Life” are my personal faves. But no second tier scribble has won me over or warmed my heart more than Dug from “Up.”

The dopey voice given to Dug the dog definitely plays into squirrel! plays into it, but I think the pooch’s simplistic view of life is really what’s so enviable. Pixar smartly included a brand new squirrel! short on the “Up” DVD — in stores today — that focuses on Dug pre-Carl & Russell life.

And as you can see from this squirrel! sneak peek, Dug’s plan to catch the bird was always filled with holes.
